This distinction is critical and its the difference between having a huge edge or a huge bill…
The smarter a model gets, the less it needs to actually be the DOER and instead it’s the orchestrator/planner.
Fable 5 researches and creates the plan then spawns subagents to handle implementation who then push the work back to Fable 5 for review. Pair that with
/loop and you’ve got a system that can run for hours but is also optimized for your budget.
You should basically never use Fable for coding, but instead use it as a planner/orchestrator.
Most of today's advanced models can implement a spec perfectly, and once done you can send the work to Fable to review.
This has been my most powerful flow so far.
